Abstract: A launching tube for use with a liquid filled tank can be sized to accommodate a submersible vehicle for dispensing into the liquid tank. The tank can be an electrical transformer or any other liquid containing tank such as but not limited to a chemical tank. The launching tube can include a valve for insertion into a launching chamber, and a tank side valve for launching of the submersible into the tank. In one form the launching tube includes an antenna for communication with the submersible and/or a base station. The launching tube can also include a sensor such as a camera, as well as an agitator. The agitator can be used to facilitate bubble removal from the inside of the launching tube.

Abstract: A submersible inspection device used for inspection of, for example, liquid cooled electrical transformers can include a number of separate cameras for imaging the internal structure of the transformer. The submersible can be configured to communicate to a base station using a number of wireless transmitters and receivers. Signals transmitted to the submersible include command signals useful to effect an action on the submersible but also a heartbeat signal to indicate health of the transmitted signal. A redundant channel selection logic is provided to switch from a channel which no longer receives a heartbeat to another channel that includes a current heartbeat. Multiple signals can be received and evaluated in software, and another signal received via a firmware radio.
